Anti-sinking mechanism for blocked cabin door of airplane
The invention belongs to the technical field of airplane blocking type cabin door anti-sinking design, and particularly relates to an airplane blocking type cabin door anti-sinking mechanism. In the cabin door opening process, when a cabin door is lifted upwards to the highest position and is about to be away from a door frame position, a plunger latch is automatically locked through a pawl, a latch shaft is prevented from rotating, and therefore the cabin door is prevented from sinking; the pawl locking position is the end of the latch crank, the arm of force is large, the stress state is good, when the cabin door is closed and is about to enter the door frame position, the pawl can be extruded through the open end of the latch groove to automatically unlock, the cabin door can sink to be closed, operation is easy and convenient, the overall structure is simple, and the weight is small.
本申请属于飞机堵塞式舱门防下沉设计技术领域，具体涉及一种飞机堵塞式舱门防下沉机构，设计在舱门打开过程中，舱门向上提升到最高位置并且即将远离门框位置时，以棘爪自动锁定锁闩，防止闩轴转动，从而防止舱门下沉，棘爪锁定位置为闩曲柄的端部，力臂大，受力状态良好，且在舱门关闭，即将进入门框位置时，能够通过闩槽敞开端挤压棘爪自动解除锁定，使舱门能够下沉关闭，操作简捷，整体结构简单，具有较小的重量。
